Purpose: This study aimed to analyze the effects and intervention methods of aromatherapy studies in nursing. Methods: A systematic literature review was conducted. Nursing literature databases were searched to identify intervention studies published in Korea between 2000 and 2011. Finally, 53 articles were included in the review. Results: The most preferred application method of aromatherapy was massage. The major dependent variables were anxiety, depression, pain, and sleep disturbance. 76.5% of the studies reported positive effects on anxiety. 93.8% of the studies reported positive effects on depression. 86.7% of the studies reported positive effects on pain. 92.3% of the studies reported positive effects on sleep disturbance. Psychometric measurements were mainly used in the studies. Only 33.9% of the studies adopted physical or physiological measurements. The most prevalent physical or physiological instrument was vital signs. Conclusion: Aromatherapy had positive effects on anxiety, depression, pain, and sleep disturbance measuring when using psychometric instruments. However, there was no sufficient evidence measuring when using physical or physiological instruments. These need to be studied using well-designed, randomized, controlled trials, and should encourage the use of both psychometric and physiological measures for aromatherapy intervention in nursing studies.

측정도구의 구조타당도는 내용타당도 이후 가장 먼저 수행되어야 할 측정 속성이다. 이를 위해 국내 간호학에서는 주로 CFA를 사용하는데, CFA로 얻을 수 없는 정보들을 제시하는 IRT/라쉬 분석도 같이 적용해 볼 것을 추천한다. 구조타당도 이외에 내적일관성 및 교차문화타당도/측정동일성 또한 측정도구의 내적구조를 확인하기 위한 것이다. 국내 간호학 측정도구 연구에서 교차문화타당도/측정동일성에 대한 검증은 거의 찾아볼 수 없는 상황이다. 따라서 앞으로는 이에 대한 평가도 시행되기를 바란다.

Purpose: The COVID-19 pandemic has increased the importance of nurses' clinical performance, and accordingly, nursing educators have emphasized students' clinical practice and performance. This study developed a Clinical Practice Self-Efficacy Scale for nursing students and examined its psychometric properties. Methods: The authors reviewed instruments for selecting items for the scale in the areas of clinical skills, communication, infection control, safety, and nursing process. After preliminary items were selected, ten experts consisting of nursing professors and clinical nurses reviewed the items considering Korean clinical and educational situations. The data for the psychometric evaluation was collected from 257 nursing students in their 2nd, 3rd, and 4th years and then analyzed. Results: The confirmatory factor analysis showed that the goodness of fit of this scale with five factors represented by 40 items was appropriate. The significant positive correlations with general self-efficacy indicated sound construct validity. The senior nursing students showed higher scores than others, as we expected. Cronbach's alpha was .94. Conclusion: The Clinical Practice Self-Efficacy Scale is appropriate for measuring Korean nursing students' self-efficacy of clinical practice. It is expected to act as a good tool to measure the effects of clinical practice education.

Internal marketing has been suggested as the approach for service organizations to be service-and customer-oriented; and the issues of internal service quality has been one of topics widely discussed in the internal marketing literature. While previous studies have attempted to develop the instrument assessing the internal service quality, ISQB(internal service Quality battery) developed by Kang et al.(2002), compared to other instruments have received some attention given its rigorous approach to measure the internal service quality. However, it has been noted that the validity of ISQB does not appear to be thoroughly examined while the reliability of the instrument seems to be secured. The current study attempts to readdress the psychometric properties of ISQB through the replication of the instrument. The empirical testing including confirmatory factor analysis and correlational analyses show that the instrument is reliable and valid in terms of its discriminant and nomological validity.

This study aimed to develop and evaluate the psychometric properties of the Thai Elderly Resilience Scale (TERS). Its conceptual structure consists of three identified domains, I AM, I HAVE, and I CAN, within the 18 components that were initially used for developing the item pool. The first draft of the scale consisted of 50 items. A psychometric evaluation of content validity reliability and construct validity was conducted. The results yielded the current version of the TERS based on Exploratory Factor Analysis (EFA) consisting of 24 items categorized into 5 factors: 1) being able to join other people, 2) being confident in life 3) have social support 4) living with spiritual security and 5) being able to de-stress and manage problems. The scale had a high internal consistency (${\alpha}=.94$). A strong positive correlation between resilience and mental health scores were found (r=.84, p<.01, n=30). The newly developed TERS would be a useful tool to assess resilience in Thai elderly and can be applied to develop further studies regarding elderly Thai people.

The purpose of this study was to identify the psychometric properties of the vocational ability scale used in the 8th Panel Survey of Employment for the Disabled in Korea by using the Rasch model. The sample data was collected from 398 individuals with intellectual disabilities. Item fitness, item difficulty, the appropriateness of the rating scale, and the separation index of the vocational ability scale were evaluated. All 15 items show an appropriate fitness level. The analysis of item difficulty indicate that modifications are required. Specifically, the need for the addition of less difficult question items is identified. The use of a 5-point rating scale is shown to decrease the test difficulty in terms of clarity and readability when appropriate and a 4-point modification is also determined as appropriate. With respect to the outcomes of the analysis, the person separation reliability value and separation index are high, and the reliability of the items is also high.

Objective: This study aimed to review scales and tests developed for or validated with children and their families that were published in the Korean Journal of Child Studies from 1984 to 2016. Specifically, the purpose of the present study was to analyze the contents and format of the selected instruments, as well as to evaluate their psychometric properties. Methods: Using several databases and journal archives from the Korean Journal of Child Studies, searches were implemented using the key terms: instrument, scale, development, and validation. Instruments from 76 selected studies were reviewed based on several characteristics, such as assessment areas, contents, respondents, responding types, and psychometric properties. Results and Conclusion: First, a majority of the reviewed instruments were developed for infants and children, whereas only one was developed for adolescents. With regard to their specific measurement domains, many instruments focused on social emotional development among children. Second, with a few exceptions, the selected studies provided appropriate evidence for the reliability of the instrument, including its internal consistency, inter-rater reliability, and spilt-half reliability. Many studies also reported on the criterion-related or construct validity of the instrument to establish its validity. Future studies need to develop instruments across diverse developmental areas that collect information from multiple sources and raters. In addition, more evidence on the reliability and validity of the reviewed instruments should be provided to demonstrate their psychometric qualities.

Background: Colorectal cancer is a serious health problem. Early detection of colorectal cancer is crucial for treatment and reducing mortality. Beliefs related to colorectal cancer have been found to be a factor in a person's decision about colorectal cancer screening programs. To determine such beliefs, a valid and reliable instrument is necessary. Objective:The aim of this study was to adapt and determine the psychometric properties of the Persian version of Champion's Health Belief Model Scale of breast cancer screening in the measurement of beliefs toward colorectal cancer (CRC) screening. Materials and Methods: The 'forward-backward' procedure was applied to translate the instrument from English into Persian. This study was conducted in Iran from June 2012 to May 2013. A convenience sample of 200 individuals aged 50 years and older was recruited from the population at the outpatient clinics in the three teaching hospitals. Validity was assessed using content, face and construct validity. To test reliability, the internal consistency was assessed by using Cronbach's alpha coefficient and test-retest (intraclass correlation coefficient) analyses. Exploratory factor analysis was used to assess the construct validity and determine the factors of adapted Champion's Health Belief Model Scale. Results: The mean age of the participants were 62.5 years (SD=10.8 years) and the majority of them (75.5 percent) were female. The results of exploratory factor analysis indicated a six-factor solution for the questionnaire (benefits, motivation and confidence, seriousness, susceptibility, emotional barriers and background barriers) that jointly accounted for 55.52% of variance observed. Cronbach's alpha of the subscales ranged from 0.57 to 0.89 and test-retest reliability ranged from 0.81 to 0.93 indicating a good range of reliability. Conclusions: The findings of this study suggest that the Persian version of Champion's Health Belief Model Scale of CRC screening has good psychometric properties and could be an appropriate measure for health beliefs related to CRC screening in national and international studies.

Purpose: The purpose of this study was to monitor the use of health-related quality of life (HRQOL) instruments in Korean studies of patients with diabetes. Methods: Of 86 Korean studies initially identified, 17 studies met the inclusion criteria. For each study, a description of the instrument and its psychometric properties were monitored by the Instrument Review Criteria of the Scientific Advisory Committee. These criteria include conceptual definition, attributes, taxonomy, reliability, validity, responsiveness, administrative mode, and language adaptations. Results: Five generic and one diabetes specific type questionnaires were identified from the 17 studies. Of those studies, conceptual definitions with the attributes of multi-dimension and subjectiveness were provided for 11 studies (71%). In the analysis of conceptual taxonomy, only 6 studies were classified as HRQOL, while other studies were done as QOL or health status. In monitoring of psychometric properties, reliability, validity, and responsiveness were reported for 88.2%, 64.7%, and 29.4%, respectively. One generic instrument was developed with a Korean population, while the other instruments were developed for Western countries. However, language adaptations were performed for only a few of the instruments. Conclusion: The psychometric properties including responsiveness of most instruments warrants further research, and the development of diabetes-specific HRQOL measurements should be sought to facilitate intervention outcomes across Korean studies of patients with diabetes.
